Resonant Wireless Power Transfer Workshop

About: Hi! I'm Staci =) If you're looking for creative hacking and making of all sorts of things, you've come to the right place. High speed board designer, power electronics practitioner, and system architect...

In this presentation we're going to use the $7 ZVS drivers made for induction heating to provide wireless power for LEDs in your fish tank, toy cars that are powered from under the track, charging your smart watch with a loop in the steering wheel of your car and another in your watch band (good coupling :) )...Etc.


First draft of slides so go easy on me...
